Hi The regular flash plugin 10.2 doesn't have vaapi (Intel) support The Chrome flash plugin (10.7?) doesn't have any vaapi or vdpau support You best option is to install the vdpau to vaapi wrapper and disable the Chrome flash plugin <a href="https://github.com/i-rinat/libvdpau-va-gl">https://github.com/i-rinat/libvdpau-va-gl</a> This will revert you back to the older 10.2 flash version which should work I think I also had to override a few settings in the flash dot file to get it to skip GPU validation along with following the instruction for the above project Its quite convoluted but least it makes YouTube work Cheers Mike <div class="gmail_quot<blockquote class=" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">[ Dave - your <a href="http://linux.ie" target="_blank">linux.ie</a> email generates bounces for me, trying redhat instead ] On Mon, Sep 9, 2013 at 11:25 PM, Sean V Kelley <<a href="mailto:sean.v.kelley@intel.com">sean.v.kelley@intel.com</a>> wrote: >> >> I'm also a bit bummed that hw acceleration of video doesn't seem to >> work on Haswell, meaning that full-screen is now a jerky mess.

Easy test: go to youtube, and watch things that are in 1080p HD. They play fine in a window (using about 70% CPU), but full-screened to 2560x1440 they play at about one or two frames per second. Non-HD content seems to be fine even full-screen. Either just because it's so much easier to do, or because some level of scaling is hw-accelerated. It may well be that I'm using chrome (and chrome seems to tend to use its own library versions), and firefox indeed seems to be a bit better. But by "a bit better" I mean closer to full frame rate in full-screen, but lots of tearing - and it was stil using 70% CPU when displaying in a window. So I think firefox is also still doing everything in software but may be better about using threads for it. My previous i5-670 which was inferior in almost every other way didn't have these problems.. It had the same 2560x1440 display.
